CORROBORATING FACTS EXTRACTED FROM MULTIPLE SOURCES

A method and system for corroborating facts extracted as attribute-value pairs from multiple sources. Facts associated with a common subject are identified and extracted from multiple sources. From the extracted facts, attributes satisfying a first corroboration requirement are identified. Attribute-value pairs satisfying a second corroboration requirement and having any of the identified attributes that satisfy the first corroboration requirement are identified. Predefined actions may be performed with respect to the identified attribute-value pairs and/or with respect to their status in a fact database.
